The original patch (early May) didn't fix it for us...

However,  I have just updated and checked the sources again,  and there
were further changes after the patch that I applied.

We still have two machines that exhibit this behaviour from time to
time - I'll update them and see if that fixes it.  If it doesn't,  I
will be able to get crashdumps.  (We've also got SCSI disks in the
machines in question).

Thanks for the additional info.

BTW on one occasion,  we fixed the *symptoms* of our problem by
repairing a disk that had bad sectors.  (This didn't show up in error
messages from the twe driver - only when we scanned the disk using
Maxtor's PowerMax tools.  After remapping the sector and rebuilding the
array - the problem disappeared).
